SPRING-SETTER.

SPECIFICATION forming part of Letters Patent No. 258,382, dated May 23,1882,

' i Application filed AugustQO, 1881. (No model.)

,To all whom it may concern:

Be it known that we, JOHN CREAGAN and CHARLES D. TYLER, J r., ofCleveland, Guyahoga county, Ohio, have invented a new and usefulImprovementin Sprin g-Setters, of which the following is aspecification, reference being had to the accompanying drawings, formingpart thereof. l a

Figure 1, Sheet 1, is a plan view of our improvement, partly in sectionthrough the line an 00, Fig. 2. Fig. 2, Sheet 1, is a sectional sideelevation of the same, taken through the line 3 3 ,Fig. 1. Fig. 3, Sheet2, is a sectional end elevation of the same, taken through the line a z,Fig. 1.

Similar letters of reference indicate corresponding parts. i

The object of this invention is. to facilitate the settingof springs andpromote convenience in adjusting the machine to give the desired form tothe springs.

A represents the frame of the machine, to the end bars of which areattached the ends of two rods, B, which extend along the inner sides ofthe side bars of the said frame to serve as sup-.

ports and guides for the sliding plates 0 D. i The plates 0 D haveupwardlyprojecting flanges upon their end edges and the end parts oftheir outer side edges to form beds for the adjustable fingers or barsE. The plates 0 D have lugs upon their ends, in the outer ends of whichare a formed half-round notches or recesses to receive, fit, and slideupon the rods B. In the faces of the plates 0 D are formed grooves toreceive the bars J, which extend across the,

space between the said plates 0 D to receive and support the spring tobe bent or set. Upon each of the plates 0 D are laid a series of fingersor bars, E, placed side by side, and the ends of which project beyondthe inner edges of the said plates 0 D. The fingers E are held down uponthe plates 0 D by the cross-bars I, which are placed upon the saidfingers E, and their ends are secured to the end flanges of the plates 0D by the screw-bolts G. The fingersE are pressed together to furthersecure them in place by screws H,whieh pass through the end flanges ofthe plates 0 D and press against the side fingers, E. The fingers E canbe conveniently released and adjusted to give any desired form to thesprings by loosening the screws G H. The end parts of the outer edge ofthe forward plate, D, rest against the end parts of a curved spring, I,the middle part of which rests against and may be: secured to theforward cross-bar of the frame-A, so that the plate D will not encountera rigid resistance when subjected to pressure in setting a spring. Thefingers E upon the two plates 0 D are so arranged that the inner ends ofeach set offingers will describe the curve to be given to the spring, asshown in Fig. l.

i To the under side of the middle partofthe rear frame, 0, is attached,or upon it is formed,

a nut, K, the screw-thread of which fits into 6 the thread of the screwL, placed below the plates 0 D and swiveled in bearin gs attached to theframe A. The rear end of the screw L projects and revolves in bearingsformed in or attached to the post M, which is strengthened in a verticalposition by a rod, N, attached to "its upper part and to the upper partof a vertical frame, 0, attached to the rear end of the frame A. Uponthe projecting rear part of the screw L are placed two fast pulleys, P,and 7 5 two loose pulleys, Q, the said loose pulleys being placed sideby side and between the two fast pulleys P. The forward pair of pulleys,

P Q, is provided with a straight belt, R, and the rear pair of pulleys,Q P, is provided with a crossed belt, S. The belts R S pass around along pulley, T, attached to the shaft U, which revolves in bearingsformed in or attached to the upper ends of the post M and frame 0. Theshaft U is designed to receive the drivingpower, which may be applied bymeans of a crank, a pulley and belt, or other suitable means.

V is a semi-cylindrical plate, which passes around the lower parts ofthe loose pulleys Q, 0 and has its end parts slotted transversely toreceive the bolts W, that pass through longitudinal slots in the arms X,which project upward and have slots formedin their upper ends to receivethe belts R S, so that both the belts can be shifted at one movement ofthe beltshipper, to bring both the belts upon the loose pulleys or tobring either of the belts upon a fastpulley, as may be required. Theslots in the plate V and arms X allow the belt-shipper to be so adjustedthat it'will move the belts the distance required. The middle part ofthe curved plate V is rigidly secured to a. bar, Y, the rear part ofwhich slides in bearings in the post M and in the short post Z, placedat a little distance from the post M and connected with it by a tie-rod,a. The forward end of the sliding bar Y is pivoted to the upper end of abar, I), the lower end of which is pivoted to the upper end of a shortstandard, 0, attached to the floor, the bed of the machine, or othersuitable support.

To the lower end of the bar I) is attached, or with it is rigidlyconnected, the inner ends of two arms, 01 e, which project, the oneoutward and the other inward, at right angles with the said bar I),makingit a double anglelever. With this construction, by moving theouter end of the arm d downward the straight belt will be shifted to theforward fast pulley P and the crossed belt to the loose pulley Q, andthe screw L will be turned forward to set the spring. When the outer endofthe arm eis moved downward thecrossed belt will be shifted to therearward fast pulley P and the straight belt to the loose pulley Q, andthe screw will be turned back to release the spring. This constructionallows separate treadles to be -of the lever g is pivoted the end of arod, t,

which; slides in hearings in hangers j and 7c. The forward hanger, j, isattached to the frame A. The rear hanger, 7c, is attached to the-rearplate, 0, so as to be carried back and forth by the said plate in itsmovements. upon the guide-rods B.

To the rod 2', upon theoppositesides of the hanger k, are attachedcollars I m, in such positions that when the plate (J is carried forwardby the movement of the screw L it will bring the hanger 7c in contactwith the. forward collar, m, and operate the belt-shifter to move thebelts R S upon the loose pulleys. In the same manner, when the plate 0is completing its rearward movement, the hanger It comes in contact withthe rear collar, 1, and shifts the:

belts to the loose pulleys. The belts are moved from {the loose pulleysto the fast pulleys to give motion to the screw L, to move the plate 0in either direction by operating the double angle-lever b d e.

To the center finger, E, secured. to the plate D, is attached,or upon itis formed, a pointm, to enter a hole in the center of the springblank,to center the said blank, and thus insure its receiving the propershape.

Having thus fully described our invention, weclaim as new and desire tosecure by Letters Patent 1. The combination of the rods B,the groovedend flanged plates, 0 D, having notched end lugs, the adjustable bars E,held down by bars F, the bolts G, the screws H, and the bars J, as andfor the purpose specified. 2. The combination, with the slide-bar Y, ofthe slotted lever g, the pivoted slide-rod 71, provided with collars Zm,and the hangers j k, one of which is attached to movable plate 0, as andfor the purpose specified.

3. The combination, with the frame 0, of the nut K, the screw L, the twofast pulleys Q,

the straight belt R, the crossed. belts S, the long pulley T ondrive-shaft U,- the slotted curved plate V, the slotted arms X, thepivoted slide-barY, and the bar b, pivoted to standard c and having armsdc, as and for the purpose specified.

4. In a spring-setter, the combination, with the sliding bar Y of thebelt-shifter, of the double an gle-lever b d e, substantially as hereinshown and described.
